Study of Digital Library Information Retrieval Model Based on Ontology
The core task of digital library is that provides good information retrieval system for the users. Traditional information retrieval technology is mainly based on keyword matching and has little semantic inferring ability. Moreover it does not provide semantic guidance for users. So information retrieval system may miss some information that users really want and return some information that users dont want. Ontology is used for digital library information retrieval in this paper. At first this paper analysis the feature and demand of the digital library, then put forward to the digital library information retrieval model based on ontology and system structure, develop the key technology, finally give the test.
